I checked alternator voltage via the cluster and it hovered around 14v even with all light and electronics on. I think that is good enough voltage to keep battery charged but probably would be ideal if it hovered around 14.5v.
Anyways, dealership in Austin wanted $560 to replace the battery! And even if I purchase the battery separately and install it myself, they still want $195 to program and register the battery! Damn thieves... how can they get away with this lol. Anyways, I did some research and seems like Walmart battery does very well in cold weather! (Farm Project YouTube Channel compared batteries). So I bought an H8 EverStart with 900CCA and 95Amp/Hr ($165 + $35 for BimmerLink) which was almost identical with my original one except that one had 90Amp/Hr on the label. In this case, coding is not required but battery registration is.
In this video I show battery replacement process and registration using BimmerLink app. I also show some features on the BimmerLink app... my car is a 2012 X5 35D with 125k mile.
Any questions, shoot!
Cheers
